Reconnecting LTE after Disconnect

jaredwolff How old is the board you’re working with?

Purchased within the last year.

jaredwolff If you’re using VSCode Zephyr Tools you can invoke zephyr-tools-monitor to monitor a different BAUD

Ah ha!

Help?

Since you’re able to communicate with the device it’s probably not a USB issue. Just to confirm, you can flip the orientation of your USB connector (turn it 180 degrees from the way you were using it) to see if that makes an improvement.

Do you only have one board to try this on Barliesque ?

jaredwolff Just to confirm, you can flip the orientation of your USB connector

With this device and USB cable I was able to install the Blinky and client_at projects, as well as upload the mfw_update app itself. Flipping the USB connector had no effect.

jaredwolff Do you only have one board to try this on

I have several devices on hand. I’ve just switched over to one of those and hit the same problem. This device is on COM11, so I used Zephyr Tools: Setup Newtmgr to switch to COM11, bauderate 1M. I installed the mfw_update app. Then used python3 update_modem.py mfw_nrf9160_1.3.1.zip com11 1000000 to attempt the upgrade. Same thing happens.

I now have a second computer I’m in the process of getting set up for modem firmware updates. I’ve run into some problems getting computer #2 setup properly: The nfed folder doesn’t appear in VS Code, giving me no way of switching over to the mfw_update project.

I’ve got one computer with which I can install the mfw_update. So I thought maybe I could use the other to perform the update. Here’s what happened there:

Barliesque if you got another machine to work, I expect to think it’s some type of issue with the Python library. In the case of the above, it looks like maybe you didn’t install the library?

**Failed to load dll** at C:\Users\usaf\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\pynrfjprog\lib_x64\NRFDFU.dll.

Do you have the command line tools installed?

https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download

Make sure you have the latest

I’ve tried downgrading both machines with: pip install "pynrfjprog<10.14"
Neither was able to complete the update.

An error was reported by NRFJPROG DLL: -220 TIME_OUT.

jaredwolff Or, another alternative, you can send it my way and I can update the modem firmware for you.

That is kind. Unfortunately, we haven’t got the time available for turnaround. Would you be up for checking things out directly with TeamViewer?

Success at last. I don’t have a clear picture of what exactly had to be done, as Brian got on with TeamViewer to have a poke around. Anyway, it looks like things are working at long last. Thank you, Jared, for your help.

Barliesque oh awesome. If you have an idea of what Brian did that would be helpful for everyone to know. Overall I’m glad you’re unstuck!!
